after receiving the 5G signal stream associated with the first SIM card from the outside, the first antenna 2051 transmits the received downlink 5G signal stream of the first SIM card to the first splitter 2041 connected to the first antenna 2051 for splitting, and then splits to obtain the 5G signal stream associated with the first SIM card and transmits the 5G signal stream to the second modem 203 for demodulation.
After receiving the 4G signal stream and the 5G signal stream associated with the first SIM card and the 4G signal associated with the second SIM card from the outside, the second antenna 2052 transmits the received downlink 4G signal stream and the 5G signal stream of the first SIM card and the downlink 4G signal of the second SIM card to the second splitter 2042 connected to the second antenna 2052 for splitting, then the received downlink 4G signal stream and the received downlink 5G signal stream of the first SIM card and the received downlink 4G signal stream of the second SIM card are split to obtain the 4G signal stream associated with the first SIM card and the received downlink 4G signal stream associated with the second SIM card, and the obtained downlink 4G signal stream and the received downlink 4G signal stream of the second SIM card are transmitted to the first modem 202 for demodulation, and the obtained downlink 5G signal stream associated with the first SIM.
After the third antenna 2053 receives, from the outside, the 4G signal stream and the 5G signal stream associated with the first SIM card and the 4G signal associated with the second SIM card, the received downlink 4G signal stream and the 5G signal stream of the first SIM card and the downlink 4G signal of the second SIM card are transmitted to the third splitter 2043 connected to the third antenna 2053 to be split, and then the received downlink 4G signal stream and the received downlink 5G signal stream of the first SIM card and the received downlink 4G signal stream of the second SIM card are split to obtain a 4G signal stream associated with the first SIM card and a 4G signal associated with the second SIM card, which are transmitted to the first modem 202 to be demodulated, and the received downlink 5G signal stream associated with the first SIM card is split to obtain a 5G signal stream associated with the first SIM card and.
After receiving the 5G signal stream associated with the first SIM card and the 4G signal associated with the second SIM card from the outside, the fourth antenna 2054 transmits the received downlink 5G signal stream of the first SIM card and the received downlink 4G signal of the second SIM card to the fourth splitter 2044 connected to the fourth wire 2054 for splitting, then the obtained 4G signal stream associated with the second SIM card is split and transmitted to the first modem 202 for demodulation, and the obtained 5G signal stream associated with the first SIM card is split and transmitted to the second modem 203 for demodulation.
After receiving the downlink 4G signal stream of the first SIM card and the downlink 4G signal of the second SIM card, the first modem 202 demodulates the downlink 4G signal stream of the first SIM card and the downlink 4G signal of the second SIM card, and transmits the demodulated 4G radio frequency signal to the baseband processing module 201 for processing.
After receiving the downlink 5G signal stream of the first SIM card, the second modem 203 demodulates the downlink 5G signal stream of the first SIM card, and transmits the demodulated 5G radio frequency signal to the baseband processing module 201 for processing.
It is particularly pointed out that it is currently in the construction and development stage of 5G networks. 5G networks have specificity with respect to 4G networks.
Depending on the requirements of the communication protocol, a complete 4G network communication link requires at least 2 antennas to implement, and a complete 5G network communication link requires at least 4 antennas to implement. In a communication link formed by at least 4 antennas of a 5G network, it is necessary to maintain one antenna to implement SRS (Sounding Reference Signal) communication between an electronic device and a base station. That is, in a 5G network communication link between an electronic device and a base station, it is necessary to keep an antenna transmitting SRS signals to the base station, and the base station evaluates the quality of downlink channels between the base station and the electronic device through the received SRS signals, thereby facilitating the resource allocation of the downlink channels between the base station and the electronic device. However, according to the requirements of the communication protocol, the SRS signal needs to be switched between at least 4 antennas of the 5G network communication link. That is, the electronic device sequentially transmits the SRS signal to the base station in a time division manner through each of the at least 4 antennas of the 5G network communication link. The SRS signal does not carry communication content of communication between the user and other users, and is only used for the base station to evaluate the quality of the downlink channel.
Therefore, in the rf circuit 200, the SRS signal can be switched between the four antennas 205. That is, in the SRS signal transmission period, the SRS signal is sequentially transmitted to the base station through one of the four antennas 205 in a time division manner, and the other antennas 205 realize transmission of the user communication content between the electronic device and the base station.
Therefore, coexistence of a 5G network and a 4G network under two SIM card situations is a problem to be solved urgently in the industry, and currently, no good solution exists.
It should be noted that, in the embodiment of the present application, the operation modes of the four antennas 205 are all set outside the transmission period of the SRS signal. That is, when none of the four antennas 205 is used for transmitting the SRS signal, the operation mode of the four antennas 205 is the operation mode set in the embodiment of the present application.
In the present application, in the case of two SIM cards, the electronic device 100 communicates with the base station through both the 5G signal of the first SIM card and the 4G signal of the second SIM card. When the radio frequency circuit 200 transmits the 5G signal (including the 4G signal stream and the 5G signal stream) of the first SIM card and the 4G signal of the second SIM card, the four antennas are shared, that is, the four antennas 205 transmit the 5G signal of the first SIM card and the 4G signal of the second SIM card, so that coexistence of the 5G network and the 4G network under the situation of two SIM cards can be realized, the number of antennas of the radio frequency circuit 200 can be reduced, occupation of the antennas on the internal space of the electronic device 100 can be reduced, and the internal space utilization rate of the electronic device can be improved.
It should be noted that, under the 5G network architecture of NSA, the transmission of radio frequency signals needs to satisfy 4G +5G dual transmission, and the reception needs to satisfy 4G (2RX) +5G (4RX), where TX is transmission (transmit) and RX is reception (receive). The transmission of 5G signals is all in TDD (Time Division duplex) mode, and the transmission of 4G signals is in TDD and FDD (Frequency Division duplex) modes. When the transmission of the 4G signal is in FDD mode, the transmission and reception of the 4G signal can share the same path.
Referring to fig. 4-5, fig. 4 is a signal transmission timing diagram when the 4G signal provided by the embodiment of the present application is transmitted in an FDD mode, and fig. 5 is a signal transmission timing diagram when the 4G signal provided by the embodiment of the present application is transmitted in a TDD mode. At this time, the electronic device 100 is only installed with the first SIM card and is not installed with the second SIM card. The 5G signal of the first SIM card adopts a 5G network architecture of NSA, that is, the 5G signal of the first SIM card has both a 4G signal stream and a 5G signal stream.
When the transmission of the 4G signal is in an FDD mode:
during the period T1, the first antenna 2051 is used for transmitting a 5G signal stream of 5G signals of the first SIM card, the second antenna 2052 is used for transmitting a 4G signal stream of 5G signals of the first SIM card, the third antenna 2053 is used for receiving a 4G signal stream of 5G signals of the first SIM card, and the fourth antenna 2054 is in an idle state (i.e., an inactive state in which neither signals nor signals are transmitted). In this period, since the 4G signal stream is transmitted in an FDD manner, the second antenna 2052 can also be used for receiving the 4G signal stream in the 5G signal of the first SIM card. Therefore, the first antenna 2051 transmits a 5G signal stream in the 5G signal of the first SIM card, and the second antenna 2052 transmits a 4G signal stream in the 5G signal of the first SIM card, so that dual 4G +5G transmission can be realized; the second antenna 2052 and the third antenna 2053 receive a 4G signal stream in the 5G signal of the first SIM card, which may implement 4G (2 RX).
In the period T2, the first antenna 2051, the second antenna 2052, the third antenna 2053, and the fourth antenna 2054 are all used for receiving a 5G signal stream in the 5G signal of the first SIM card, and 5G (4RX) may be implemented.
When the transmission of the 4G signal is in TDD mode:
during the period T1, the first antenna 2051 is used for transmitting a 5G signal stream of the 5G signals of the first SIM card for the first time, the second antenna 2052 is used for transmitting a 4G signal stream of the 5G signals of the first SIM card, and the third antenna 2053 and the fourth antenna 2054 are in an idle state. In this period, since the transmission of the 4G signal stream is in TDD mode, the second antenna 2052 is not available for receiving the 4G signal stream in the 5G signal of the first SIM card, and the reception of the 4G signal stream in the 5G signal of the first SIM card needs to be completed in other periods or through other antennas. Therefore, the first antenna 2051 transmits a 5G signal stream in the 5G signal of the first SIM card, and the second antenna 2052 transmits a 4G signal stream in the 5G signal of the first SIM card, so that 4G +5G dual transmission can be realized.
In the period T2, the first antenna 2051, the second antenna 2052, the third antenna 2053, and the fourth antenna 2054 are all used for receiving a 5G signal stream in the 5G signal of the first SIM card, and 5G (4RX) may be implemented.
In the period T3, the first antenna 2051 is used for transmitting the 5G signal stream in the 5G signal of the first SIM card for the second time, the second antenna 2052 and the third antenna 2053 are used for receiving the 4G signal stream in the 5G signal of the first SIM card, and the fourth antenna 2054 is in an idle state, so that 4G (2RX) can be implemented.
In the period T4, the second antenna 2052 and the third antenna 2053 are used for receiving a 4G signal stream in the 5G signal of the first SIM card, and the fourth antenna 2054 is in an idle state, so that 4G (2RX) can be implemented.
When transmitting a 5G signal stream in the 5G signal of the first SIM card, the first antenna 2051 is a main set antenna, and is used for transmitting the 5G signal stream in the 5G signal of the first SIM card and receiving the 5G signal stream in the 5G signal of the first SIM card; the second antenna 2052, the third antenna 2053 and the fourth antenna 2054 are all diversity antennas and are only used for receiving 5G signal streams in the 5G signals of the first SIM card.
When transmitting a 4G signal stream in the 5G signal of the first SIM card, the second antenna 2052 is a main set antenna, and is used for transmitting the 4G signal stream in the 5G signal of the first SIM card and receiving the 4G signal stream in the 5G signal of the first SIM card; the third antenna 2053 is a diversity antenna and is only used for receiving 4G signal streams among the 5G signals of the first SIM card.
It should be noted that only one antenna is needed for the main set antenna to simultaneously transmit and receive the 5G signal of the first SIM card. The diversity antenna may include a plurality of antennas, thereby implementing MIMO (Multiple-Input Multiple-Output) reception of the 5G signal of the first SIM card. Thus, the radio frequency circuit 200 may implement both primary set transceiving of 5G signals and diversity MIMO reception of the first SIM card.
Referring to fig. 6 to 7, fig. 6 is another signal transmission timing diagram when the 4G signal provided by the embodiment of the present application is transmitted in an FDD mode, and fig. 7 is another signal transmission timing diagram when the 4G signal provided by the embodiment of the present application is transmitted in a TDD mode. At this time, the electronic device 100 is not only installed with the first SIM card (the white square is the signal transmission of the first SIM card), but also installed with the second SIM card (the black square is the signal transmission of the second SIM card). The 5G signal of the first SIM card adopts a 5G network architecture of NSA, that is, the 5G signal of the first SIM card has both a 4G signal stream and a 5G signal stream.
When the transmission of the 4G signal is in an FDD mode:
during the period T1, the first antenna 2051 is used for transmitting a 5G signal stream of the 5G signals of the first SIM card for the first time, the second antenna 2052 is used for transmitting a 4G signal stream of the 5G signals of the first SIM card, the third antenna 2053 is used for receiving a 4G signal stream of the 5G signals of the first SIM card, and the fourth antenna 2054 is in an idle state. In this period, since the 4G signal stream is transmitted in an FDD manner, the second antenna 2052 can also be used for receiving the 4G signal stream in the 5G signal of the first SIM card. Therefore, the first antenna 2051 transmits a 5G signal stream in the 5G signal of the first SIM card, and the second antenna 2052 transmits a 4G signal stream in the 5G signal of the first SIM card, so that dual 4G +5G transmission can be realized; the second antenna 2052 and the third antenna 2053 receive a 4G signal stream in the 5G signal of the first SIM card, which may implement 4G (2 RX).
In the period T2, the first antenna 2051, the second antenna 2052, the third antenna 2053, and the fourth antenna 2054 are all used for receiving a 5G signal stream in the 5G signal of the first SIM card, and 5G (4RX) may be implemented.
During the period T3, the first antenna 2051 is used for transmitting the 5G signal stream of the 5G signals of the first SIM card for the second time, the second antenna 2052 and the third antenna 2053 are used for receiving the 4G signals of the second SIM card, and the fourth antenna 2054 is in an idle state. In this time period, the radio frequency circuit 200 interrupts transmission of a 4G signal stream in a 5G signal of the first SIM card, and is configured to receive network injection information of the second SIM card, so as to achieve dual-card dual-standby of the first SIM card transmitting data traffic and the second SIM card network injection.
When the transmission of the 4G signal is in TDD mode:
during the period T1, the first antenna 2051 is used for transmitting a 5G signal stream of 5G signals of the first SIM card, the second antenna 2052 is used for transmitting a 4G signal stream of 5G signals of the first SIM card, and the third antenna 2053 and the fourth antenna 2054 are used for receiving a 4G signal of the second SIM card. In this period, since the transmission of the 4G signal stream is in TDD mode, the second antenna 2052 is not available for receiving the 4G signal stream in the 5G signal of the first SIM card, and the reception of the 4G signal stream in the 5G signal of the first SIM card needs to be completed in other periods or through other antennas. Therefore, the first antenna 2051 transmits a 5G signal stream in the 5G signal of the first SIM card, and the second antenna 2052 transmits a 4G signal stream in the 5G signal of the first SIM card, so that 4G +5G dual transmission can be realized.
In the period T2, the first antenna 2051, the second antenna 2052, the third antenna 2053, and the fourth antenna 2054 are all used for receiving a 5G signal stream in the 5G signal of the first SIM card, and 5G (4RX) may be implemented.
In the period T3, the first antenna 2051 is used for transmitting a 5G signal stream in a 5G signal of the first SIM card, the second antenna 2052 and the third antenna 2053 are used for receiving a 4G signal stream in the 5G signal of the first SIM card, and the fourth antenna 2054 is in an idle state, so that 4G (2RX) can be implemented.
In the period T4, the second antenna 2052 and the third antenna 2053 are used for receiving a 4G signal stream in the 5G signal of the first SIM card, and the fourth antenna 2054 is in an idle state, so that 4G (2RX) can be implemented.
The difference between the signaling timing diagram shown in fig. 7 and the signaling timing diagram shown in fig. 5 is that, when the first SIM card performs 4G +5G dual transmission in a period T1, the idle third antenna 2053 and the idle fourth antenna 2054 are used for receiving network injection information of the second SIM card, so as to achieve dual standby for the first SIM card to transmit data traffic and the second SIM card to inject network.
When transmitting a 5G signal stream in the 5G signal of the first SIM card, the first antenna 2051 is a main set antenna, and is used for transmitting the 5G signal stream in the 5G signal of the first SIM card and receiving the 5G signal stream in the 5G signal of the first SIM card; the second antenna 2052, the third antenna 2053 and the fourth antenna 2054 are all diversity antennas and are only used for receiving 5G signal streams in the 5G signals of the first SIM card.
When transmitting a 4G signal stream in the 5G signal of the first SIM card, the second antenna 2052 is a main set antenna, and is used for transmitting the 4G signal stream in the 5G signal of the first SIM card and receiving the 4G signal stream in the 5G signal of the first SIM card; the third antenna 2053 is a diversity antenna and is only used for receiving 4G signal streams among the 5G signals of the first SIM card.
When transmitting the 4G signal of the second SIM card, the second antenna 2052, the third antenna 2053, and the fourth antenna 2054 are all diversity antennas and are only used for receiving the 4G signal of the second SIM card.
It should be noted that only one antenna is needed for the main set antenna to simultaneously transmit and receive the 5G signal of the first SIM card. The diversity antenna may include a plurality of antennas, thereby implementing MIMO (Multiple-Input Multiple-Output) reception of the 5G signal of the first SIM card and the 4G signal of the second SIM card. Therefore, the radio frequency circuit 200 can implement both the main set transceiving and diversity MIMO receiving of the 5G signal of the first SIM card and the diversity MIMO receiving of the 4G signal of the second SIM card, thereby implementing dual-card dual-standby with coexistence of 4G and 5G.

Accordingly, the control circuit 206 may control the first modem 202 to enable the four antennas 205 to intermittently transmit the 4G signal stream of the 5G signal of the first SIM card and the 4G signal of the second SIM card.
It is understood that the control circuit 206 may also be integrated in the baseband processing module 201, for example, the control circuit 206 and the baseband processing module 201 may be integrated as a baseband processing module chip.
